U.S. Route 30 Business (US 30 Bus.) is a 19-mile (31 km) business route of US 30 in Chester County, Pennsylvania. The route follows the former alignment of US 30 between Sadsbury Township and East Whiteland Township, passing through Coatesville, Downingtown, and Exton. US 30 follows a freeway bypass between these two points. The present alignment of US 30 Bus. was originally part of a turnpike called the Philadelphia and Lancaster Turnpike that was completed in 1794. The state took over the turnpike at the beginning of the 20th century. In 1913, present-day US 30 Bus. was incorporated into the Lincoln Highway, an auto trail that ran from San Francisco east to New York City. The Lincoln Highway through Pennsylvania became Pennsylvania Route 1 (PA 1) in 1924. US 30 was designated concurrent with PA 1 west of Philadelphia in 1926, with the PA 1 designation removed two years later. US 30 was widened into a multilane road through Chester County in the 1930s. In the 1960s, US 30 was moved to a freeway bypass around Coatesville and Downingtown, with US 30 Bus. designated onto the former alignment of US 30. In 1995, US 30 Bus. was extended east when US 30 was extended to bypass Exton.

History
US 30 Bus. westbound in Exton
The present-day alignment of US 30 Bus. was constructed as part of the Philadelphia and Lancaster Turnpike, a turnpike connecting Lancaster to Philadelphia. The turnpike company was incorporated in 1792 and the road was completed in 1794.[4][5] The Philadelphia and Lancaster Turnpike was built with a stone and gravel surface and was the first long-distance turnpike constructed in the United States, leading to a movement to improve roads across the country. The turnpike also opened up settlement to the Northwest Territory past the Ohio River and provided cheap transportation between the coastal areas and the "bread basket" region around Lancaster.[6] By 1843, the rise of the railroads and the canals reduced the use of the Philadelphia and Lancaster Turnpike, and the road fell into disrepair and saw decreased usage through the later part of the 19th century.[6] The state acquired the Philadelphia and Lancaster Turnpike at the beginning of the 20th century.[5]
Following the passage of the Sproul Road Bill in 1911, the present-day alignment of US 30 Bus. was designated as part of Legislative Route 142, which ran from Lancaster east to Philadelphia.[7] In 1913, the current routing of US 30 Bus. became part of the Lincoln Highway, an auto trail that ran from San Francisco east to New York City.[8] The Lincoln Highway within Pennsylvania was designated as PA 1 in 1924.[9][10] With the creation of the United States Numbered Highway System in 1926, US 30 was designated concurrently with PA 1 on the Lincoln Highway west of Philadelphia.[10][11] The concurrent PA 1 designation was removed from US 30 in 1928.[12][13][14]
In the 1930s, the section of US 30 through Chester County was widened to a multilane road.[15] By 1960, a freeway bypass for US 30 was proposed to run from just east of the PA 10 intersection to east of Downingtown.[16] In 1963, the freeway bypass of US 30 between east of PA 10 and east of Downingtown was completed, with US 30 Bus. designated onto the former alignment of US 30.[17][18] In December 1995, the US 30 freeway was extended east to bypass Exton, ending at an interchange with the US 202 freeway.[19][20] As a result, US 30 Bus. was extended east through Exton along the former alignment of US 30 to its current eastern terminus.[19][21]
